The advanced AI model, which the tech giant undoubtedly sees as central to its aspirations of leading the highly competitive AI race, is now said to be months behind its internal schedule. This delay stems from the model’s reported failure to consistently meet Google’s stringent internal performance benchmarks, particularly in critical areas such as coding capabilities. The setback comes at a pivotal moment, with rival firms like OpenAI and Anthropic rapidly advancing their own foundational models, raising concerns within Google about its competitive standing.
The detailed account of these developmental struggles emerges from a comprehensive report by Bloomberg, which cites multiple sources including individuals intimately familiar with the project and a collective of ten current and former Google employees. This internal friction and perceived lag have reportedly generated considerable frustration among engineers, researchers, and management teams across various divisions within Google. A prevailing sentiment among some is a growing apprehension that competitors are not merely keeping pace, but are actively extending their lead in the rapidly evolving artificial intelligence landscape.
The Genesis of Gemini and Google’s AI Ambitions
Google’s journey in artificial intelligence is long and storied, marked by groundbreaking research and development that has shaped the modern AI paradigm. From the acquisition of DeepMind, a world-leading AI research lab, to the development of TensorFlow, an open-source machine learning framework that became an industry standard, Google has consistently been at the forefront. Crucially, Google Brain researchers were instrumental in authoring the seminal 2017 paper "Attention Is All You Need," which introduced the Transformer architecture—the very foundation upon which modern large language models, including OpenAI’s GPT series and Google’s own Gemini, are built.
The initial unveiling of the Gemini family of models in late 2023 was met with considerable fanfare and positioned as Google’s direct and comprehensive answer to OpenAI’s GPT-4. Gemini was introduced in various sizes—Gemini Ultra for highly complex tasks, Gemini Pro for scaling across a wide range of applications, and Gemini Nano for on-device applications—demonstrating Google’s ambition to integrate AI capabilities across its vast ecosystem, from cloud services to Android devices. The company explicitly stated its goal to lead the "AI race," a term that encapsulates the intense competition among tech giants to develop the most powerful, versatile, and commercially viable artificial intelligence.
However, Google’s path in this race has not been without its challenges. The initial rollout of its Bard chatbot, a precursor to Gemini’s public-facing applications, experienced a notable misstep involving inaccurate information during a public demonstration, leading to a significant dip in market valuation. These early stumbles underscored the immense pressure and scrutiny associated with deploying cutting-edge AI, particularly when attempting to balance innovation with accuracy, safety, and reliability. The strategic importance of Gemini, therefore, cannot be overstated; it represents Google’s concentrated effort to leverage its deep research capabilities and extensive resources to reclaim or solidify its perceived leadership position in the AI domain.
A Detailed Chronology of the Reported Delays
The timeline surrounding Gemini 3.5 Pro’s development highlights a departure from Google’s anticipated release schedule. Industry observers and internal stakeholders had widely expected Google to officially unveil Gemini 3.5 Pro during its annual developer conference, Google I/O, held in May. This event typically serves as a key platform for Google to showcase its latest technological advancements and strategic initiatives to its global developer community and the broader tech world. The absence of a prominent announcement regarding Gemini 3.5 Pro at I/O, despite the introduction of other AI advancements like the Flash model, was an early indicator of potential internal issues.
According to reports, the critical period leading up to the May conference saw growing internal struggles. Engineers and researchers were reportedly grappling with the model’s performance, particularly its ability to handle complex coding tasks—a capability increasingly seen as a cornerstone for advanced AI models, especially for enterprise applications and the development of sophisticated AI agents. In a significant effort to rectify these shortcomings, Google reportedly updated the model’s training data late last month, specifically targeting improvements in its coding proficiencies. However, the subsequent evaluation of these changes yielded disappointing results, failing to bring the model up to the company’s demanding internal benchmarks.
This sequence of events has pushed Gemini 3.5 Pro "months behind schedule." To put this into context, Google had previously released Gemini 1.0 Pro in December 2023, followed by Gemini 1.5 Pro in February 2024, which introduced a groundbreaking 1-million-token context window. More recently, the company introduced Gemini 1.5 Flash in May 2024, a lighter, faster, and more cost-efficient version designed for rapid deployment. The expectation was for 3.5 Pro to represent a substantial leap beyond these iterations, offering significantly enhanced reasoning and multimodal capabilities. The reported delay for 3.5 Pro, therefore, marks a notable deviation from what had appeared to be a relatively rapid iterative development cycle for the Gemini family, contrasting sharply with the consistent stream of updates from its primary competitors.

A deficiency in this area could significantly limit Gemini 3.5 Pro’s appeal and utility in the competitive market.
The Bloomberg report suggests that Google’s immense size and organizational structure may paradoxically be contributing to these delays. The development of AI coding tools, for instance, is not confined to a single team but is reportedly being pursued by multiple divisions across the company, including Google Cloud, DeepMind, and Android. While such a decentralized approach might foster innovation in theory, in practice, it can lead to fragmented efforts, potential redundancies, and a lack of unified strategic direction, ultimately slowing down progress on a single, cohesive product like Gemini 3.5 Pro.
Furthermore, the report highlights the bureaucratic hurdles inherent in preparing such a significant model for release. Several layers of stakeholders are reportedly involved in the approval and deployment process, ranging from technical leads and product managers to legal, safety, and ethical review boards. While rigorous review processes are essential for responsible AI development, particularly given Google’s past experiences with AI missteps, an overly complex or elongated approval chain can impede the speed required in a fast-moving industry.
Adding to these internal dynamics is the reported competition for computing power. High-performance computing resources, particularly specialized GPUs, are the lifeblood of modern AI development, essential for training and fine-tuning large language models. The report indicates that Google employees face internal competition for access to these critical resources when attempting to utilize AI internally for their projects. This scarcity, if pervasive, could bottleneck research, development, and testing efforts, thereby contributing to delays and frustration among teams reliant on these powerful computational engines.
